It wasn't this hard before, Rosell made it the way it is, from what I have heard.
As opposed to Bayern which is kind of like a corporation that issues stocks with companies such as Adidas and such holding significant shares, we are truly a club owned by the members. Therefore, I can understand why the club wants to have some sort of control over the membership. Otherwise, you are going to have outside groups that will just eat up the membership by massively applying to become members and then decide/manipulate the fate of the club.
Arrogant? Come on Ryu. Hardly. As much as you can brag about Bayern, it is global footprint can not match the likes of Barca, Real Madrid, Manchester United. I remember reading somewhere not too long ago that on social media Barca has the most number of supporters/fans. And I can tell you where I am, there are many more Barca/RM/ManU fans than Bayern fans.
